I had ' AirPrint' not IJ series this whole time and was going mad trying to work out how to start getting my settings straight. THAT was a super helpful point!! Thank you.

[Using Mac OS (latest OS) / Canon PRO-100s / Kodak Premium photo paper 240gsm jrhoffman75 and I dont feel like I understand it any better. i've wasted hours on this and it's still not as good as it should be. I really wish there was some straightforward way to set this up. It's still printing a fraction washed out but at least it looks vaguely normal. The only thing that seemed to return it to normal was actually going into Lightroom and Selecting : Colour Management > Managed by Printer. then did a test print and the magenta was still there. I then tried adjusting the colour on screen until it looked kind of ok again like it should printed. I tried assigning a colour profile in Photoshop that matched to see what would happen and it was ghastly (Using Canon-Pro 100s Other Glossy Paper). following the idea of letting Lightroom / photoshop manage colour. I then tried various things from this forum.

That explanation got me to re-install the printer using the correct driver.
